Coordination Compounds — Chemistry STD 12 Science — Question

→ The Crystal field model is successful in explaining the formation, structures, colour and magnetic properties of coordination compounds to a large extent.
→ However, from the assumptions that the ligands are point charges, it follows that anionic ligands should exert the greatest splitting effect. The anionic ligands actually are found at the low end of the spectrochemical series.
→ Further, it does not take into account the covalent character of bonding between the ligand and the central atom. These are some of the weaknesses of CFT.
